需要用到的环境
能运行电脑版钉钉的Windows或者Mac用于获取机器人地址
能长期稳定运行node.js环境的电脑或者服务器(需要网络连接)，可以是你自己的电脑，服务器，软路由，群晖，你们公司闲置的电脑或者docker一个node
【可选】，如果需要天气预报，需要自行申请百度开发者api密钥，百度天气API开发文档, 以及申请密钥
获取钉钉机器人地址
- 下载电脑版钉钉，下载地址
- 新建一个群，加入你想通知的人，如果你想只发送给自己，踢掉其他人即可。
- 群设置 => 群智能助手 => 添加自定义机器人(webhook) => 安全设置勾选加签
- 最后复制好webhook地址和加签密钥
服务端部署
- 在你的服务器(或电脑)上安装好node.js环境，官方下载，Linux和mac请自行查阅安装教程安装，Linux推荐使用docker安装
- 检查安装，windows下打开Node.js command prompt程序，输入
node -v,出现版本号即为正常，检测PATH环境变量是否配置了Node.js，点击开始=>运行=>输入cmd=> 输入命令path，显示中有node.js即为正常。Linux同理。 - 在你喜欢的位置新建一个项目文件夹，命名随意，打开文件夹，新建一个index.js
安装依赖
安装yarn
npm i -g yarn安装定时模块
yarn add node-schedule安装加密
yarn add crypto安装node-fetch // 用于获取天气预报
编辑package.json，增加yarn add node-fetch"type": "module"，(放在json第一级)
加入功能
import schedule from 'node-schedule'
import fetch from 'node-fetch'
import crypto from 'crypto';
